1. What are the two common mechanical-draft cooling tower arrangements?
2. How does an induced-draft cooling tower differ from a forceddraft tower?
3. What is cooling tower fill material?
A 4-bit shift register is shifted six times to the fight. If the initial content of the register is 1101, find the content of the register after each shift if the serial input is 101101.
A 110-V rms, 60-Hz source is applied to impedance Z. The apparent power entering the load is 120 VA at a power factor of0.707 lagging. (a) Calculate the complex power. (b) Find the rms current supplied to the load.
As usual neglecting edge effects, find the capacitance as a formula containing S,d, e1, ande2. Test that yourformula gives the correct well-known result for the capacitance ofa parallel-plate capacitor with uniform dielectric when you put e1 = e2.
1) Determine the transfer of second-order highpass filter with a cutoff frequency of 900 Hz and passband gain of 1 using a butterworth type. 2) Design a filter for your transfer function from question.1 using the sallen-Key topology.
The characteristic impedance is 50 . Use CAD to plot the insertion loss versus frequency.
The cylindrical coaxial cable with the cross section shown below, has inner and outer radii of 5mm and 15mm respectively. The dielectric parameters are; er=2, signma=5*10^(-10) S/m and Ur=1
a) Explain why no hole is generated by the electron excitation involving a donor impurity atom. (b) Explain why no free electron is generated by the electron excitation involving an acceptor impurity atom.
A certain amplifier has an open circuit voltage gain of unity,and input resistance of 1 MΩ, and an output resistance of100Ω. The signal source has an internal voltage of 5 Vrms and an internal resistance of 100kΩ. The load resistance is 50Ω.
